MECHANISM FOR SLIDING DOORS, DRAWERS, AND THE LIKE.

Application filed May 28,

To all whom it may 0011 cam.

Be it known that I, HANS EDVARD KJoL- SETH, a subject of the liing of Norway, residing at Porsgrund, Norway, have 111V6I1 t ed certain new and useful Improvements in Mechanisms for Sliding Doors, Drawers, and the like; and I do hereby declare the following to be a full, clear, and exact dc scription of the invention, such as w ll enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to suspension llnk mechanisms for sliding doors, drawers and the like, allowing of a substantially rectilinear displacement of the same.

The object of my invention s to supply a simple and effective suspenslon arrangement of this kind, having fewer and sun pler parts than those before known. A. prominent feature is also that the door in being closed is lowered toward the floor so as to make the opening below to amimmum.

Figure 1 is a side view of a sliding door with its sliding mechanism.

Fig. 2 is a side view of the mechanism applied to a drawer.

As will be seen from the drawing the mechanism consists of two main parts, v1z. the sliding mechanism, whose parts have the reference numbers 1, 2 and 3, and the door mountings having the reference numbers 4 to 7.

A bar 1 is fastened to the wall above the door. To this bar are hinged links 2. To the free ends of said links 2 are hinged bailshaped or T-shaped suspension link levers 3, in which the door is suspended.

The door mountings comprise angular mountings 1 and 5, sunk flush into the corner of the door, and through these parts 4 and 5 a screw 6 is put. This screw 6 is provided with a nut 7, which may be moved by aid of a nail or the like, inserted through a hole in the angular part 4:. The upper ends of the screws 6 are hinged to the lower end of the links 3, the door being thus suspended in these links 3. By aid of the nut 7 the door may be raised or lowered so as to come into the right position relative to the door frame. It will be understood that the path of the suspended door will be a function of the relative positions of the five hinge Specification of Letters Patent.

move along a path suitable for its purpose.

S0 for instance for a sliding door an approximately rectilinear path with a slight lowering toward the floor in the closing moment is preferable.

If a double set of suspension bars and links, as illustrated in Fig. 2, are used, a doubling of the transverse movement may be obtained. Thereby I may for instance be enabled to draw a drawer quite outside the chest to which it belongs. In this Fig. 2 the bars 8 and 8 correspond to the bar 1 in Fig. 1. The links 9 and bails 10 have the same functions as the parts 2 and 3 in Fig. 1. The bar 11 has the special function to transfer the movement of one half of the mechanism to the other half. If the bars 8 are fastened to the wall of the chest A and the bars 8 to the drawers, the bar 11 will act so as to enable the drawers B being drawn quite outside the wall, carried in this position by the rest of the parts in combination with this bar 11.

It will be understood that through varying the relative positions of the hinge points, it will be possible to vary the path of the suspended object quite at will.

Claims.

1. In a suspension link mechanism for the substantially rectilinear displacement of sliding doors, drawers and other objects, having to perform to and fro movements, the combination of two links, hinged at their lower ends to stationary points and a third intermediate link lever having three hinge points arranged in a triangle, the two upper of such hinge points being hinged to the free upper ends of said links, and the third of said hinge points serving as a suspension joint for the object to be suspended and guided.

2. In a suspension link mechanism for the substantially rectilinear displacement of sliding doors, drawers and other .objects having to perform to and fro movements, the combination of two links, hinged at their lower ends to stationary points and a third intermediate link lever having three hinge points arranged in a triangle, the two upper of such hinge points being hinged to the free upper ends of said links, and the third of said hinge points serving as a suspension joint for the object to be suspended and guided along a substantially rectilinear path with a slight lowering of said path at its end positions.

3. In a suspension link mechanism for the substantially rectilinear displacement of sliding doors, drawers and other objects having to perform to and fro movements, the combination of two links, hinged at their lower ends to stationary points and a third intermediate link lever having hinge points arranged in a triangle, the two upper of such hinge points beinghinged to the free upper ends of said links, and the third of said hinge points serving as a suspension o1nt forthe ob ect to be suspended, said systom of hinged links and link levers being interconnected with a corresponding system ans EDVARDKJOLSETH Witnesses LAVINLUND,
